Oh yes, and the big thing is you can use regular salt...sodium cloride, but no sea salt or iodized salt. Remeber it is a low iodine not a NO iodine diet.
Go to Thyca.org. They have a great cook book, sound advice, and lists of things you should and should not eat as well as stuff in food to avoid. Best advice is no fish or anything from the ocean (certain additives are made of seaweed). Limit meats to small amounts and no sea salt or iodized salt. I made several things ahead of time and froze them, worked well. Potatoes without skin were a staple. lots of veggies and fruits.
